CM1150V settings for xfinity
After a week of intermittent internet service, I called Comcast / Xfinity only to be told that my modem settings are not up to date and I should contact Netgear. My modem has the latest Comcast pushed firmware so not sure what settings to adjust. Same frustrating experience with both service provider and modem manufacturer not able to help.
Any ideas?

There isn't any user settings on CM series modems as this is just a modem only.
Please post a copy and paste of the modems connection status and event log page.

https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-routerBe sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

I'm using a RAX80 WiFi router. The setup has been working well for over a year. Recently Comcast lost all services in our neighborhood for several hours. Internet has not been good since it was restored, but they tell me the signal has checked out perfectly and my modem is the problem since the settings are not compatible with their recent 5G LTE upgrade!
Power Levels and Correct and Un-Correctables are good.
However there are lots of criticals in the events log that the ISP needs to review and resolve.
IF the modem was working well before the outage and it's not after the outage, the ISP needs to look into this. I don't think it's the modem here.
